Product Description

Metallic, like ink or blood”

Certified water flavour standard used to train professional tasters to recognize and scale the intensity of metallic character.

Metallic characters are contributed to water either from natural ground and soil conditions or from electrochemical or microbe-mediated corrosion of cast iron pipework. Ferrous compounds generally impart a metallic mouthfeel to water, but high levels may lead to discolouration of affected water.

Food grade | free from sensory impurities | extensively tested | safe to smell and taste.

IMPORTANCE

Ferrous ions Impart a metallic mouthfeel to water. High levels of ferrous ions may be associated with discolouration of the water supply and – in the extreme – the formation of ‘red water’. Addition of one capsule of this flavour standard to one litre of water produces a colourless solution, whereas use of two capsules in one litre of water produces a discoloured solution.

ORIGINS

Metallic taints are derived from contamination of water with metal ions, either from natural ground and soil conditions or from electrochemical or microbe-mediated corrosion of cast iron pipework.

HOW TO TASTE

The best way to assess metallic flavour in water is to take a little sample into your mouth, move it around with your tongue for a few seconds then swallow it. To confirm the presence of a metallic taint, rub a little of the water onto the back of your hand and check for a metallic odour.
